British NVC community M20

NVC community M20 (Eriophorum vaginatum raised and blanket mire) is one of the mire communities in the British National Vegetation Classification system.

It is a comparatively localised community. There are two subcommunities.

Community composition

Two constant species, Common Cottongrass (Eriophorum angustifolium) and Hare's-tail Cottongrass (Eriophorum vaginatum), are found in this community.

No rare species are associated with the community.

Distribution

This community is found throughout northern England. It is extensive in the southern Pennines, but more local elsewhere. It is also found locally in eastern Scotland and south Wales. It is mainly found within tracts of upland blanket bog, but also locally on raised bogs.

Subcommunities

There are two subcommunities:

  • the so-called Species-poor subcommunity
  • the Calluna vulgaris - Cladonia spp. subcommunity
gollark: I suppose my best defense would be switching to IP over Avian Carriers and a lot of paper to run computations on.
gollark: There's not really a well-supported thing which *is* an actual vector image format though.
gollark: More attack surface → more bugs → more bad.
gollark: Yes.
gollark: There was some cut-down SVG format for mobile devices which dropped JS and similar features, but then added it in in a later version for some deranged reason?!
